What happened to my 2020 download? I get a critical error on my MAC. Cannot find the download file that I paid for.

I purchased the deluxe 2020 version of TurboTax.  I installed and opened it on my MAC but today when I opened it to check on updates I get a critical error.  I deleted and reinstalled the software but get the same error.  I cannot find my download file online.  Any help?
